Comparison of Customized and Standard Total Ankle Prostheses

Patients who underwent ankle prosthesis implantation procedure with an anterior approach were involved in a longitudinal skin incision of about 12-15cm anterior to the tibio-tarsal joint in supine position. Once the deep layers were reached, passing through the anterior tibial tendon and extensor hallucis longus tendon sheath, the tibio-tarsal joint was then exposed. The operator proceeds to astragalic and tibial resections, once the appropriate size of implants was selected, the final components were implanted. In both groups, the basic prosthetic design approach will be 'three-component,' that is, with congruent mobile meniscus interposed between the tibial and astragalic components. At the end of the procedure, orthopedic walker boot was placed for 3 weeks, and progressive weight allowed.
